What You Should Do When Being Passed
When Another Vehicle Passes You
If another vehicle passes you on the left on a two-lane highway, decrease your speed slightly and keep to the right. It will help the other driver to pass safely. It is imperative to slow down if the other vehicle lingers on your left side or when driving in heavy traffic and there are small gaps between vehicles.
Continue at normal speed when the vehicle has safely passed and is ahead. Never increase your speed while being passed; it may put the other driver in danger.
Being Passed on the Right
If you are being passed on the right by many vehicles, you are likely driving slower than the traffic flow. Even if you go at the posted speed limit, you should move into the right lane and allow other drivers to pass you on the left.
Never tie up traffic in the left lane. It is not only a common cause of road rage; it may also trigger dangerous driving maneuvers by others.
Before moving over to the right, check your blind spot. It is often harder to see vehicles on your right side. Be particularly aware of small vehicles, like motorcycles.
DMV Written Test Questions
Questions on the written DMV test will usually focus on proper lane usage. If you are driving slower than the traffic flow, you must stay in the right-hand lane. Remember, it is a violation to “impede or block the normal and reasonable movement of traffic except.”
Generally, it helps if drivers use the left-most lane only when overtaking other vehicles.
If you can choose among three lanes in your direction, pick the center lane for the smoothest driving until you are ready to exit or turn.
Blocking Traffic Put You at Risk
Blocking traffic flow by driving in the left lane on a multi-lane road is often an indication for a law enforcement officer to pull you over on suspicion of driving under the influence.
